Slowing down isn't what necessarily needs to be fixed here, it's the whole "contributing something useful" thing that needs to be fixed. You could slow down but if you're still posting just "lol" onto a topic about how a magnitude 7 earthquake revealed an ancient civilization known as "Haiti", not only are people going to be kinda mad but also they'll think you're an asshole for making a really bad joke so soon about Haiti oh man I am going to hell for that one.

But yes. Slowing down != content. There are days where I posted well over 20 times but it's okay because I bring cool art and fantastic lulz something useful to the conversation.

The (rather invisible) point I'm trying to make here is that comics are either supposed to A) be short and hilarious or B) rather long and tell a story. Sure you can use them for just about anything, but the above points are what they're most commonly used for. Your tiny strips do neither of these things. It also makes no difference how good or bad the art is if the story or joke make up for it, for example, this man is a comedic genius, and is therefore able to make a hilarious pun using flat characters with no depth. The only difference between them is that they have different colored shirts. (Aside from Cyanide and Happiness, his art is still rather nice iirc)

Bottom line, Jokes / Story > art. Your drawing can be as crappy as horse feces, but if the joke or story is good you're all set. Keep that in mind.
